This publication is devoted to study of effectiveness of hydrogen electrode saturation in the electrochemical Harned cell. The fastest and fullest saturation of hydrogen electrode is one of the key criteria when using electrodes being a part of State primary standard pH SS 54-2011. Level of hydrogen electrode saturation ultimately influences the attainment of a steady state time in the electrochemical cell, thus determining the total time necessary for defining the hydrogen parameter value.

Key words: hydrogen electrode, saturation, Harned cell.
